Dear Cabal-ers I have downloaded a binary installation of GHC 7.8.2, for Linux. Now I want to install regex-compat. First I had to deal with the http_proxy problem, in my last email. But now I get this:
cabal install regex-compat Resolving dependencies... Downloading regex-posix-0.95.2... Configuring regex-posix-0.95.2... Building regex-posix-0.95.2... Preprocessing library regex-posix-0.95.2...

The exception was: ExitFailure 1 simonpj@cam-05-unx:~/code/HEAD-1$ cabal install regex-base Resolving dependencies... All the requested packages are already installed: regex-base-0.93.2 Use --reinstall if you want to reinstall anyway. simonpj@cam-05-unx:~/code/HEAD-1$ So regex-base is already installed, but cabal isn't using it for regex-posix; nor is it installing regex-base-0.93.2. This seems to break the user's-eye view of the Cabal claim that it'll download and install the dependencies. Any thoughts? Simon
